Connect the pink wire to a ignition+ wire(use your test light and find a wire that has current only when the key is switched on). The microtech is turned on when the pink wire receives a positive signal.

I thought that was the purpose of running the pink wire to the tan wire on the plug coming out of the coil

that's probably what's throwing the error light. hook everything up and you should be ok.

Don't take this the wrong way, but that wiring job is designed for failure. Here are some examples why:

Electrical tape is not to be used EVER to insulate electrical connections, especially in an engine bay. The heat will quickly dry it out, the adhesive contains acids that will eat the connection, and moisture will get trapped inside. Assuming you soldered, the solder will begin to corrode after a year or so. If the wires are just twisted, then the joint will become high resistance and fail in short order.

The proper way to connect two wires in a permanent fashion is to use adhesive lined heatshrink tubing. Solder all joints and then shrink the tubing over the joint with about 0.5CM excess on each end of the joint.

Standard crimp terminals don't have any protection against corrosion and will quickly fail. There are crimp terminals with built in heat shrink boots that you shrink over the wire after you have crimped, but they still corrode at the actual spade terminal. You can prevent this by using dielectric grease on the terminal itself and the wire before it's crimped.

In addition, there are specific relay sockets designed to accept a standard automotive relay. The contacts are encased in plastic to prevent shorts and they come with wire leads to solder onto. Dielectric grease should be applied to the contacts before the relay is installed.

I don't know what to say about this. If it lasts to the end of the driveway, I would be surprised.

After alot of messing around and stepping back and at it again i finally got the car started today. I loaded one of the base maps that was posted in the sticky thread and the car stays on and runs a little ruff but it runs.

Aaron i will be taking of the manifolds here in the next few days and cleaning up and shrink tubing the soldered connections.

I would also like to thank everyone that responded to Fb II's thread your advice came in handy with my install.
